MIPI Battery Interface (BIF) Standard

Summary

ORIGA™2, the first MIPI BIF Device and its features

Consumer Safety & Counterfeits

The ORIGA™ solution

Battery Interface Addresses Market Needs

• Mobile device battery industry

produced 1.5 billion batteries last

year – all using non-standard,

proprietary battery interfaces

• A commonly accepted battery

interface will save design time &

effort, improve time to market,

reduce chipset space and improve

cost margins

• Low cost, single-wire interface is

the only one in the industry for

mobile devices

Main features of BIF

• Supports both smart & low cost battery

• Fast Battery pack presence detection

• Single wire low cost interface up to 250kbit/s

• Supports single master, multi-slave configuration

• See MIPI BIF presentation every show day at 14:00

ORIGA™2 is the first device on the market to do this, but what sets us clearly apart is something else….

Do YOU think this is a problem ?

EDN Europe; March 2006

Companies are working to strengthen

anti-counterfeiting efforts to protect

brand integrity and consumers from

potentially dangerous, counterfeit products.

Why Authentication ? To protect end customers from dangerous clones !

Head line examples:

• S Korea probes 'cell phone death'

• Exploding mobile phone kills man in China

• Laptop explodes at Japanese conference

Security has many components and it all comes down to the weakest point

1. System Security – Asymmetric Elliptic Curve Cryptography

2. Hardware security

3. Security of Production & Personalization sites, supply chain.
